You cannot reason with people like this... Your only choice for survival is to defeat them.
They need to be humiliated and too ashamed to express their backwards anti-science, anti-fact, anti-humanity views again... Their malignant stupidity has cost our nation dearly, killed countless people.
An example needs to be made of them so strongly that it echoes through future generations.
Their great-grandchildren need to learn of their malicious stupidity in grade school.
Long after they are dead, it will be widely agreed that it would have been better if they had never lived.
I wonder if they care that that will be their most enduring legacy.
